               At least two points of the subdivision not over 800 feet apart shall be designated
               by course and distance (tie) from a readily discernible reference marker. If a corner
               is within 2,000 feet of the U.S. Geodetic Survey or the state grid system coordinated
               monument, or the county-coordinated system, if such exists, then this corner shall
               be marked with a monument so designed by computed X and Y coordinates which shall
               appear on the map with a statement identifying this monument to an accuracy of at
               least 1:10,000. When such a monument is not available, the tie shall be made to some
               pertinent and readily recognizable landmark or identifiable point, physical object
               or structure. However, if in the opinion of the board, a subdivision is of such small
               size, or if there is an existing tie within a reasonable distance of the subdivision,
               this shall not be required.

               Each marker shall have embedded in its tip or attached by suitable means, a metal
               plate of non-corrosive material and marked plainly with the point, the surveyor's
               registration number, the month and year it was installed, and word "marker," "monument"
               or "control corner." A marker shall be set 30 inches in the ground unless this requirement
               is impractical because of unusual conditions. In flood zones set out in the FEMA rate
               index maps, one marker in each subdivision is required to have its elevation recorded
               on the metal plate.
